A Procedural Language in JavaScript powered by V8
=================================================
plv8 is a shared library that provides a PostgreSQL procedural language powered
by V8 JavaScript Engine. With this program you can write in JavaScript your
function that is callable from SQL.
REQUIREMENT
-----------
plv8 is tested with:
- PG: version 8.4, 9.0, 9.1 and 9.2dev (maybe older are allowed)
- V8: version 3.6.2
- g++: version 4.5.1
Also all tools that PostgreSQL and V8 require to be built are required.
INSTALL
-------
Make sure V8 include files are in the system include directories, or you can
place them in $(PLV8DIR)/../v8/include. Run make
$ make install
and create language via
$ psql -c 'CREATE EXTENSION plv8'
in 9.1, or in the prior versions
$ psql -f plv8.sql
to create database objects.
TEST
----
plv8 supports installcheck test. Make sure set custom_variable_classes = 'plv8'
in your postgresql.conf and
$ make installcheck
EXAMPLE
-------
CREATE OR REPLACE FUNCTION plv8_test(keys text[], vals text[])
RETURNS text AS $$
var o = {};
for(var i=0; i
